Title: Method and device for processing image and image pickup device
Inventor: IKEDA EIICHIRO
IPC: H04N5/335
Filed: 1994-11-18
Abstract: PURPOSE: To prevent the inactive area of the spectral sensitivity of a color from being erroneously discriminated by discriminating areas while using a bottom threshold value for a saturated area and using a peak threshold value for a noise area among the threshold values set for each color. CONSTITUTION: A color interpolation processing circuit 12 investigates chrominance signals stored in a memory, interpolates omitted picture elements and transmits threshold value signals in four colors through an LPF 8 to a dynamic range extension processing part 9. After the luminance level of a standard image photographed by proper exposure is matched with the luminance level of a non-standard image photographed by non-proper exposure as threshold value setting processing, the values of both the image signals are plotted. Namely, the picture element value of one image is taken as an X axis, |non-proper image-proper image | is calculated as a Y axis, its average value is calculated, and a saturated value area T is provided just before the maximum value of this value.  Then, the areas are discriminated by using the bottom threshold value for the saturated area and using the peak threshold value for the noise area. At a threshold value setting part 95 of the processing part 9, the threshold values are set to all the colors and the white inactive area is discriminated.

Abstract: PROBLEM TO BE SOLVED: To provide the method of manufacturing laminated electronic component capable of reusing a gravure roll as well as contributing to cut down the manufacturing cost. SOLUTION: Numerous protrusions 11 are provided on the whole surface area of a gravure roll 1 so that the printing parts 13 in a specific shape may be formed on the roll surface by covering any needless recessions 11 with a coating material 12 thereby enabling the printing parts 13 in different shapes to be easily formed on the roll surface by removing the coating material 12 for recoating. That is, in case the conductor layer shape is different even in the same kind of part or different kinds of component are to be manufactured, the triuble of preparing an exclusive gravure roll for engraving new recession group can be saved thereby making the reuse of the gravure roll feasible thus contributing to cut down the manufacturing cost.

Abstract: PURPOSE:To prevent mis-detection of a carrier sense circuit due to an interfer ence signal and to prevent crosstalk or the like by selecting an intermediate frequency of a reception circuit to be a specific integer multiple of a speech channel interval frequency. CONSTITUTION:With a frequency division ratio of a reference divider 12d set to be 1/1699 and a frequency reference signal of a reference oscillator TCXO 14 set to be 21.2375MHz, when the signal is received by the divider 112d, an output of a frequency signal of 12.5kHz is given to a phase comparator 12c, which generates a reference frequency of 12.5kHz. Then, a 2nd IF signal frequency is 21.7MHz. Since a 2nd local oscillating signal uses the reference signal of the TCXO 14 in common, the same frequency is given to a 2nd MIX 7. Then a frequency of a 2nd IF signal is 462.5kHz, which is a multiple of 37 of the frequency 12.5kHz and a frequency synthesizer circuit 16 comprising a VCO 13, a PLL 12 and a TCXO 14 locks the frequency and receives the signal. Thus, 2nd-4th harmonic signals with respect to 462.5kHz give interference, but since the 2nd IF signal due to the interference signal has a frequency of a multiple of 12.5kHz, no interference frequency signal exists.

Abstract: PURPOSE: To obtain a large-sized good-quality single crystal reduced in micropipe defects by newly taking out a wafer from an SiC single crystal with the specified crystal face grown as a seed crystal and again growing a single crystal by sublimation and recrystallization. CONSTITUTION: A seed crystal 8 is mounted on a seed crystal mounting part 7 in a graphite crucible 4, and an SiC material 5 is charged. A crystal inclined to a (0001) face at an angle of 60-120 deg. is used as the first seed crystal 8. The crucible 4 is evacuated, the raw material is heated to 2000 deg.C, and the crucible is kept at about 600Torr while introducing an inert gas. The crucible is then evacuated to 1-50Torr, and the growth of a single crystal is started at the raw material temp. of 2100-2500 deg.C. The seed crystal temp. is 40 to 100 deg.C lower than the raw material temp., and the temp. and pressure are adjusted so that the growth rate of the single crystal is controlled to 0.5-1.5mm/hr. The obtained ingot 2 is cut to form a (0001) wafer 3, and an SiC single crystal is grown on the (0001) face from the same material with the wafer as a second seed crystal 8.

Filed: 1989-11-02
Abstract: PURPOSE:To improve the extent of vibration and noise characteristics by slinging and locking a crankshaft to a support member supported on an inner ring end of an upper bearing through a locking member, and installing a minute clearance between a stepped surface of the crankshaft and a floating control plate. CONSTITUTION:A crankshaft 6 is locked to a support member 25 supported by an end of an inner ring 23 of an upper bearing 21 after being slung by a snap ring 26, and a minute clearance 28 is secured in a space between a stepped surface 27 of the shaft 6 and floating control plate 24. Dead weight of the shaft 6 works on the inner ring 23 of the bearing 21 as preload in the axial direction via the support member 25. In consequence, any possible noise being produced out of the bearing 21 due to axial vibration and resonance in the shafting is prevented. In addition, excessive flotage on the upper part of the shaft 6 attendant upon dropping and conveyance is also prevented when the stepped surface 27 of the shaft 6 comes into contact with the floating control plate 24. Moreover, since the whole thrust force of the shafting is supported only by the rolling type bearing 21, sliding loss due to the thrust force is thus abated.
